Notes
| Notes on operation | Separating plate PLC-ATP must be installed for voltages larger than 250 V (L1, L2, L3) between identical terminal blocks in adjacent modules. Potential bridging is then carried out with FBST 8-PLC... or FBST 500.... |
| Notes on operation | The PLC-ATP separating plate should be installed for safe isolation between adjacent modules |
| Assembly instruction: | The PLC-ATP separating plate is required at the start and end of every PLC terminal strip. |
| Notes on operation | The system installer must ensure the touch protection of the product (at voltages > 25 V AC/60 V DC). The product is a built-in device without protection against direct contact. |
